Abstract

The utility model relates to a tooth claw type maize straw pulverization field returning machine. The machine comprises a straw cutting hob assembly, a straw picker, a straw feeding roller, a pulverizing room, a suppressing roller, a suspension frame, a gearbox and a transmission system. The straw cutting hob assembly, the straw picker, the feeding roller and a rotor in the pulverizing room are successively installed on the side plates at the two sides of the field returning machine by a bearing. The stripped maize straw is cut off from the root, the straw is picked up by the picker, and then the straw is enforcedly fed in the pulverizing room so as to carry out supporting pulverization and return to field. The picking process can avoid missing the straws, tooth claw entering in soil or soil-mixing pulverization; the abrasion of the tooth claw can be relieved, and the supporting pulverization can reduce the operation power consumption and improve the straw pulverization field returning quality.

Description

Claw type corn stalk crushing and returning machine

(1) Technical field

The utility model relates to a claw-type corn stalk crushing and returning machine, in particular capable of simultaneously cutting corn stalks, picking up straws, forced feeding of straws and supporting crushing and returning to the field. the

(2) Background technology

At present, there are mainly three types of corn straw returning machines: hammer claw type, Y type throwing knife type and straight knife type. When carrying out straw returning operations, most of them are crushed with single support or no support, and quite a lot of straw is torn. Yes, the fibers are longer. When working on uneven ground, the hammer claws or blades are easily in contact with the soil, resulting in faster wear, greater power consumption, and reduced operating efficiency. The quality of straw returned to the field is not good, and it will increase the difficulty of raking straw and power consumption when cultivating the soil. The straw cannot be completely buried when the plow is used to plow the land, which directly affects the sowing of wheat; if conservation tillage is implemented, wheat will be free Tillage seeders are easy to be blocked, which will also affect the quality of sowing, and even cause seedling pressure. the

(3) Contents of the invention

In view of the above problems, the utility model provides a claw-type corn stalk crushing and returning machine, which can simultaneously cut corn stalks, pick up straws, force-feed and crush and return them to the field. It overcomes the deficiencies such as incomplete crushing, severe tool wear, and high power consumption of the existing field returning machine. the

A claw-type corn stalk crushing and returning machine includes a stalk cutting hob assembly, a straw picker, a straw feeding roller, a crushing chamber, a pressing roller and a transmission system. the

The stem cutting hob assembly includes a cutter shaft, a hob, fastening bolts and bearings, the stem cutting hob assembly can float up and down according to the ground conditions; the blade is fixed on the cutter shaft by the fastening bolt, and the cutter shaft Install the side plate of the returning machine through the bearing. The hob pulley drives the hob to rotate, cutting off the crop stalks from the roots for pickup by the picker. The height of the hob from the ground can be adjusted to avoid cutting soil. the

The straw picker is mainly composed of spring teeth, spring tooth installation shafts, D-shaped slideways, picker shafts, etc. The height of the straw picker spring teeth from the ground can be adjusted; the picker spring teeth are fixed on the spring tooth installation shafts. The spring tooth installation shaft is installed on the fixed disk, and it is driven to rotate by the pickup shaft. The crank arm and the roller at one end of the spring tooth installation shaft move in the D-shaped slideway, so that the spring tooth installation shaft itself also has a certain rotation, so that the spring teeth sometimes stretch out and sometimes shrink to complete straw picking, lifting and pushing actions. , feed the picked straw into the crushing chamber. the

The straw feeding roller is a pair of raised rollers, and the upper roller adopts a floating type, which can force-feed the corn straw into the crushing chamber; the crushing chamber is composed of a shell, fixed claws fixed on the shell, and a crushing rotor; The crushing rotor mainly includes a shaft and movable claws; the crushing chamber is composed of an upper and lower shell, and the fixed claws are fixed on the shell, and the crushing chamber is equipped with a crushing rotor, and the movable claws are fixed on it, and the fixed claws and the movable claws are arranged alternately. , when the crushing rotor rotates, the movable claws pass over the fixed claws, cutting, beating, kneading and cutting the straw in the crushing chamber to make it crushed and returned to the field. the

The pressure roller is installed behind the field returning machine; the stalk cutting hob, straw picker, feeding roller, crushing chamber, and pressing roller are installed on the field returning machine in sequence; the picker bar, suspension frame and gearbox are installed On the upper part of the field returning machine; the right side plate, left side plate, pulley, sprocket and other transmission systems of the field returning machine are installed on both sides of the field returning machine. the

The transmission system includes gearboxes, pulleys and sprockets, etc., which are used to distribute the power transmitted by the tractor to working parts such as hobs, pickers, feeding rollers, and crushing rotors.

The stalk cutting hob assembly, the stalk picker, the feeding roller and the crushing rotor are sequentially installed on the side plates on both sides of the returning machine through bearings. the

When working, the stalk cutting hob first cuts off the corn stalks for the picker to pick up. The picker picks up the broken straw and transports it to the feeding roller, and the feeding roller forces the straw into the crushing chamber. The fixed claws in the crushing chamber cooperate with the movable claws on the rotor to crush the straw by cutting, beating and kneading, and throw it back to the ground. The pressure roller is installed at the back of the field returning machine, which is used to compact the crushed straw and play a role of depth limit. the

The beneficial effect of the utility model is that the plucked corn stalks are cut from the root, picked up by a picker, and then forced to be fed into the crushing chamber for crushing with support and returning to the field. By picking up, it is possible to avoid straw omission, teeth and claws entering the soil or crushing of mixed soil, and reduce the wear of teeth and claws; adopting supported crushing can reduce operating power consumption and improve the quality of straw crushing and returning to the field. the
